I was wondering if it's possible to create a single continuous line with Geometry Nodes. I want to make a cable that intersects predefined Empty objects but as you can see the line is broken.
Yes, this is possible, but actually not very practical.
The hurdle is that an "Empty" is empty, as the name suggests.
You get the position of the object directly with the node
Object Info, but you can't use
Instance on Points or
Realize Instances or similar with this object, because it's empty and doesn't return anything during an evaluation.
The only possibility you have is to process the locations directly and transfer them to a curve.
In this example I transfer the start point and end point to the curve, subdivide it and then set the center point.
